Definitions

  • the present invention relates to a rubber-elastic membrane.
  • Such membranes are used in particular for the air and weather-protected connection of ends of rail vehicles.
  • the prior art includes rubber-elastic walls, e.g. Partitions between two wagons of rail vehicles. They are intended to form a seal against weather, smoke and dust. These walls comprise an externally visible lamella made of highly elastic material, for example highly elastic rubber. On the inside of this slat, a corrugated fabric, which is embedded in plastic material, such as rubber or similar material, is attached to the slat.
  • the outer lamella When moving one another, for example in curves, of the car ends equipped with a connection transition made of this material, the outer lamella is stretched due to its elastic property, the inner layer also being pulled out and the folds or waves being flattened until the inner one Layer is in its stretched final state, so that the pulling out of the wall is finished.
  • a second wall construction of this type lies on the inside opposite the former, the surface facing inwards again being designed as a flat, sheet-shaped surface, while the folds or corrugated layer is fastened in the manner described.
  • This elastic partition wall will absorb the stresses occurring in the longitudinal direction of the train, especially in curves, due to an increase in the distance between the outer parts of the wagon with considerable elastic deformation. However, it is also a deformation in any other direction, e.g. not possible in height and / or side, because the selected inner surface with fabric insert does not allow this due to its structure and shape.
  • An annular connection of two vehicles in the form of a flexible envelope has also become known. It consists of two parts, one of which is connected to one of the ends of the vehicle.
  • the two-part casing is provided with cross shafts, which serve to compensate for changes in the distance between the two car ends in the direction of travel.
  • This transverse corrugation however, only permits insufficient spatial changes in the position of the two car ends relative to one another.
  • This possibility of adapting the shape in the event of a spatial relative change in the position of the ends of the wagons is above all a requirement if the two ends of the wagons are relatively close to one another or if the space has a small width.
  • the present invention aims to provide a rubber-elastic membrane which extends in all three directions, i.e. spatially, in the respective necessary sense, can be deformed essentially stress-free.
  • Such a rubber-elastic membrane is characterized by the features of the characterizing part of claim 1.
  • the features contained in the subclaims relate to special embodiments of the subject matter of claim 1.
  • FIG. 1 shows two rail vehicle ends 1 which are connected to one another by a connecting bellows 3.
  • This bellows has two corrugated side surfaces 4 in the direction of travel, as well as a humped floor surface 6 and a cover surface 7 of this type.
  • the upper vehicle edges are designated 9 and 10 and their respective displacements correspond to the displacements of the two rail vehicle ends 1, as seen from above and from the side.
  • the humped bottom surface 6 and the likewise humped top surface 7 can be changed in the three directions essentially stress-free and therefore, regardless of the mutual position of the ends 1, their movements can be carried out practically with minimal stress. Not only is their lifespan extended accordingly, but the risk of sudden tearing, even with sudden changes, is extremely low.
  • Fig. 2 shows an embodiment of a rubber-elastic membrane with bumps 15, which are arranged in longitudinal bump rows 16 and transverse bump rows 17. In between are longitudinal valleys 19 and transverse valleys 20.
  • This membrane is also three-dimensionally deformable, this being done practically stress-free to the extent required.
  • These membranes are made of appropriate rubber qualities, which, however, allow the necessary deformation options and therefore the material properties and the shape of the humps must be selected accordingly.
  • the rows of longitudinal or transverse bumps can also be arranged offset to one another.
  • the humps 25 have a round cross section. They are separated from one another by valleys 26. These valleys 26 and 27 meet at intersections 28.
  • the bumps arranged in rows are at right angles to one another and are symmetrical. It is of course possible to provide the angles of the rows differently, as can be seen, for example, from FIG. 6 with its kite rectangles 30.
  • the section in FIG. 7 shows that the humps and the valleys are designed as pyramids 34 and valley levels 32. While FIG.
  • FIG. 6 has dragon quadrilaterals 30 when viewed from above, other figures such as rhombuses, rhomboids, quadrangles, polygons, squares or rectangles can also be selected.
  • FIG. 8 shows a top view of a rubber-elastic membrane with different bumps, namely kite quadrilaterals 36 and oval bumps 37. It is also possible to design such rubber-elastic membranes differently in different directions with regard to deformation properties, which is not only due to the changing properties Material thickness, but also by appropriate arrangement of humps and valleys and their shapes is achieved.
  • Fig. 9 shows an example of application of such rubber-elastic membranes, such as are used for railcart transitions, the bellows-shaped transition shown here has 40 side parts with corrugated side surfaces 4 and a humped bottom surface 6 and a humped top surface 7, as these are explained with reference to the other figures .
  • This version of guumi-elastic membranes is extremely important, in particular for the production of transitions between two ends of the inner vehicle with a small mutual distance, since large deformations must be survived without damage, particularly in the case of transverse displacements.
